first embodiment

Referring to FIG. 1, a lamp 100 includes a removable cover 10 and a main body 11.

The main body 11 includes a lamp housing 111, a printed circuit board (PCB) 112, at least one light emitting element 113, and a threaded base 114. The lamp housing 111 defines a socket 115 with a threaded inner surface (not labeled) and configured for receiving the PCB 112 and the at least one light emitting element 113.

The lamp housing 111 is made of a heat conductive material such as metal and is electrically insulated from the threaded base 114 and thermally connected with the PCB 112. The PCB 112 is electrically connected to the at least one light emitting element 113 and fixed on the socket 115. The at least one light emitting element 113 can be, for example, a light emitting diode (LED) chip. Heat generated by the at least one light emitting element 113 can be transmitted to the lamp housing 111.

The removable cover 10 is connected to the lamp housing 111 and configured for enclosing and protectin...

second embodiment

As shown in FIG. 3, the lamp 200 in accordance with a second embodiment includes a removable cover 20 and a main body 21. The main body 21 includes a lamp housing 211, a printed circuit board (PCB) 212, at least one light emitting element 213, and a threaded base 214. The lamp housing 211 has a socket 215.

The light emitting element 213 can be a light emitting diode or light emitting diode chip.

The printed circuit board (PCB) 212 is received in the socket 215. The light emitting element 213 is electrically connected to the printed circuit board (PCB) 212. The inside wall of the socket 215 is threaded.

The removable cover 20 includes a light-transmission portion 201 and a connection portion 202. The connection portion 202 engages the threads of the socket 215 of the lamp housing 211. Light from the at least one light emitting element 213 is emitted from the light-transmission portion 201.

The removable cover 20 is a transparent body, and the cover can be resin, epoxy resin, silicone, po...

Abstract

A lamp includes a main body and a removable cover, and the main body includes a lamp housing, a printed circuit board (PCB), at least one light emitting element, and a threaded base. The lamp housing defines a socket configured for receiving the PCB and the at least one light emitting element, and the PCB is electrically connected to the at least one light emitting element and fixed in the socket. The removable cover includes a light-transmission portion and a connection portion, the connection portion connects to the end of the lamp housing with the socket, and the light-transmission portion is opposite to the socket. Light from the at least one light emitting element is emitted from the light-transmission portion.

Description

BACKGROUND1. Technical FieldThe present disclosure relates to lamps with replaceable covers providing different luminosities according to user's need.2. Description of the Related ArtA commonly used lamp cannot be separated from its cover, and comprises a specific luminosity. When the lamp cover burns out, the whole lamp must be discarded. It wastes dispensable resources. Furthermore, the traditional lamp has a specific luminosity and cannot be replaced with other luminosity because the traditional lamp cover is fixed to the main body of the lamp. It is noted that the lamp cannot be replaced with other lamp covers providing different luminosities according to need.Therefore, it is desirable to provide a lamp which can overcome the described limitations.BRIEF DESCRIPTION OF THE DRAWINGSMany aspects of the disclosure can be better understood with reference to the drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly...
